Specification of Application filed July 24,

T 0 all whom it may concern:

Be it known that I, LoUIs SrocKnR, a citizen of the United States, residing at Stithton, in the county of Hardin and State of Kentucky, have invented new and useful Improvements in Yarn-lVinding Machines, of which the following is a specification.

This invention relates to yarn winding machines for winding yarn on tubes to color the same, the principal object of the invention being to provide means for twisting the yarn as it is being Wound upon the tubes in such a way that after the yarns are drawn off the tubes there will be no twist left in them and all the ends will have. the same tension and there will be no slack ends as is the case when the yarn is wound on a common winder.

Another object of the invention isto provide means whereby the yarn is twisted in one direction as it is being wound upon the tube from one end to the other and in an opposite direction as it is being wound upon the tube in an opposite direction.

A further object of the invention is to provide means whereby the twisting mechanisln is moved in a path parallel to the tube carrying roller and is then automatically caused to travel back-over this path, such means comprising a worm shaft engaging a by the twisting mechathe direction of rotation of the worm shaft at each end of the travel .of the twisting mechanism.

his invention also consists in certain other features of construction and in the combination and arrangement-of the several parts, to be hereinafter fully described, illustrated inthe accompanying drawings and specifically ointed out in the appended claims.

In describing my invention in detail, reference will be had to the accompanying drawings wherein like characters denote like or corresponding parts throughout the several views, and in which Figure 1 is a front view of the invention.

Fig. 10 is a view of a modification.

In these views 1 indicates the frame of the apparatus in which is journaled the shaft 2 which carries the fluted roller 3. This shaft is connected with the main drive shaft 4.- by the gears 5, the main shaftl being provided with the fast and loose-belt pulleys 6. Vertically movable weights 7 engage the uprights 8 and the tube shaft 9 has its reduced ends engaging recesses 10 formed in the lower ends'of said weights so that the tube on said shaft is pressed into engagement with the fluted roller by said weights. The weights may be held in any desired position upon the uprights 8 by means of the eccentric 11 carried by each weight and adapted to be moved into andout of. engagement with the lined plate 12 by the lever 13. This lever is held in position with the eccentric pressing the plate against the upright by means of a spring 14 which has one end con nected with the weight and its other end to an adjustable clio 15 movable in a slot 16 formed in said lever.

A worm shaft 17 is also mounted in the frame in front of the fluted roller and this shaft is connected with the pulley shaft 18 by means of the gears-l9, said shaft 18 being-provided with the loose pulleys 20 and the fast pulley 21, these pulleys being connected with the pulleys 6 by the belts 22. A worm member 23 engages with the worm shaft 17 and this member is held against rotation by means of an arm 24 thereon engaging with a sleeve 25 which is slidably mounted on the shaft 18. The member 23 carries a circular upright frame 26 in which is rotatably mounted, preferably by ball bearings, a disk 27 which is provided With the openings 28 throughwhich the yarns are adapted to be threaded. This disk has connected therewith a circular rack 29 which engages a rack bar 30 carried by the frame and arranged parallel to the shaft 17. An arm 31 is connected with the member 23 and this arm has its free end bent upwardly and provided with a guiding eye 32.

In order to cause the worm shaft 17 to rotate in a reverse direction when the worm member 23 nears the end thereof I provide therewith belt shifting means for reversing the rotation of the shaft 18. uch means include a longitudinally movable shifter bar 33 mounted in guides in the frame and having a pair of loops 34; therein for engaging the belts. As shown one of these belts is Cir crossed so that as this cross belt is moved into engagement with the fast pulley the shaft 18 will be driven in one direction and when the straight belt is placed in engagement with the fast pulley 21 the shaft 18 is driven in an opposite direction. When either belt is engaging with the fast pulley the other belt is placed on one of the loose pulleys by the shifter mechanism. The bar 33 is connected by a link 35 with a rotatable disk 36, located on a shaft 37. This shaft 37 is provided with a beveled gear 38 which meshes with a gear 39, loose on shaft 40 which is geared to shaft 18 by the gears ll. The gear 39 is connected to one end of a coil spring 42 the other end of which is connect-- ed with an adjustable collar 43 located on shaft 40. Thus when the shaft 40 is rotated by shaft 18 the spring will be wound up and cause the gear 39 to rotate the shaft 37 and the disk by the gear 38. This movement of the disk is prevented, however, by means of a latch bar at engaging one of a pair of projections l5 formed on the periphery of the disk 36. The latch bar is adapted to move out of engagement with said projections by a trigger 4L6 pivotally mounted on the disk and provided with a pair of arms 47 for engaging said latch bar. This trigger is actuated by the twisting mechanism by means of a longitudinally movable rod L8 having stops as thereon for engaging the trigger and other stops which are adapted to be struck by the worm member 23 as said member nears the end of its travel in either direction.

The yarns are passed through the holes in disk 27 and through eye 32 and are passed around the tube on shaft 9. The weights are then lowered to press the tube against the fluted roller and then the belts are shifted to cause the winding mechanism to travel from one end of the worm shaft to the other. The fluted roller will be rotated at the same time so as to wind the yarns on the paper tube. As the worm member 23 travels along the worm shaft the disk 27 will be revolved by its rack engaging the rack 30 and thus the yarns will be twisted. winding mechanism nears one end of its movement the member 23 will strike one of the stops 50 so as to move the rod 48 longitudinally and cause one of the stops 49 to strike the trigger and cause said trigger to move the latch bar out of engagement with the projection on the disk. This will freesaid disk and permit the spring 42 to rotate the same and this movement 0 the disk will direct its connection with the shifter bar 33, move said bar to shift the belts and thus reverse the rotation of the shaft 18 and the worm shaft, Thus the worm member 23 will return to its starting point and then disk 27 will be rotated in a r verse direction. Thus the yarn will be As soon as the r twisted one way as long as the twisting 'iea'hanism moves from one end of the tube to the other and in the other direction the twister is reversed so that after the yarns are drawn off from the tube there will be no twist left and the yarns will have the same tension and there will be no slack ends hanging down as is the case when the yarn is wound on a common winder.

In the modification I substitute an endless chain 51 for the worm shaft and bolt the yarn guide to this chain. The chain passes over a flange pulley 52 and a sprocket wheel 53. The sprocket wheel 53 is carried by shaft 5a which is geared to the pulley shaft 55 by the gears 56. In other respects this modification is the same as that above described.

It is thought from the foregoing description that the advantages and novel features of my invention will be readily apparent.

I desire it to be understood that I may make changes in the construction and m the combination and arrangement of the several parts, provided that such changes fall within the scope of the appended claims.
